I have VMWare Ubuntu 11.10 guest hosted on Win7. When behind a proxy, I am able to browse with chrome / firefox but all other network activity does not work (i.e. curl, system update, apt-get, etc.)

Running ifconfig returns:

eth0  Link encap:Ethernet  HWaddr 00:0c:29:99:15:5a  
      inet addr:  Bcast:  Mask:

      collisions:0 txqueuelen:0 
      RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

I have set the proxy via the Network window and applied the settings globally (before doing that I was also unable to use web browsers). When I am not behind proxy, then everything works fine. If I ping some web site it does resolve the destination IP but ping itself doesn't work.

What am I missing?

  • The host is behind the proxy? – Tim Jan 12 '12 at 16:43
  • Yes, the windows host is behind proxy. – Aaron Jan 12 '12 at 17:59

Since your host is behind a proxy, you will need to activate "socks" through either the host or guest (I recommend the host).

Basically, only web browsers are often "set up" for utilizing proxies, to get all OTHER traffic to also pass through, you have to push all traffic through socks which in turn pushes it through the proxy for you.

    Assuming the proxy supports socks... – Zoredache Jan 12 '12 at 18:27
